Automotive Service Mechanics

Automotive service mechanics mainly deal with basic auto maintenance and preventative care. Some common procedures include oil changes, tire rotations and electrical repairs. Experienced mechanics may also repair or replace the components of brake, exhaust or cooling systems. Due to the technological advances in the industry, most mechanics are also familiar with computer diagnostic tools and electrical systems.

Although there are no formal training requirements for employment as an auto mechanic, you may benefit from a technical or community college training program. The U.S. Bureau of Labor Statistics (BLS) reported that automotive service technicians and mechanics earned a mean annual salary of $39,060 as of May 2012 (www.bls.gov). However, mechanics who can perform a variety of repairs may receive higher pay.

Automotive Body Mechanics

Automotive body mechanics fix damaged body panels or frames. Typically, they repair vehicles involved in collisions. Because every job requires an individualized approach, you'll need extensive knowledge of structural and cosmetic repair techniques to work in this field. You also need to know how to work with materials such as metals, plastics and glass.

Employers generally prefer workers with formal training and, in some cases, voluntary certification from the National Institute for Automotive Service Excellence (ASE). These credentials may increase your earnings potential, according to the BLS. As of May 2012, the mean income for automobile body mechanics was $41,840 annually.

Diesel Service Mechanics

Because of their efficiency and power, diesel engines are commonly used in larger vehicles such as trucks and buses. As a diesel mechanic, you can specialize in the maintenance and repair of not only diesel engines, but also these vehicles' electrical systems and transmissions. You may also provide service and repair for heavy equipment like tractors, combines and bulldozers.

Due to the specialized nature of diesel engine repair, you'll probably need to complete a postsecondary training program to find a job. As a result, mechanics in this field received some of the highest pay. The BLS reported that the national mean earnings for diesel engine specialists and truck and bus mechanics were $43,660 annually in May 2012.
